IMHO: There really is no substitute for mocking an upgrade before you do it in production. I rather spend hours during the day figuring out what broke vs hours in the middle of the night during a change window. If your configuration is only LTM , upgrades are usually pretty easy. Its when you have other modules such as GTM,ASM,APM, that the upgrade process can break.

If you haven't done a 10 to 11 upgrade over several devices you might say that, but after the sixteen pairs of upgrades I've done using LTM, GTM, ASM, and APM I can say that each one had a different unique problem along with a similar set of issues that did not show up in a mock lab.
